NM400 Steel Plate
Product Details
What is NM400 Steel Plate?
The NM400 steel plate is extensively used in a variety of industries including mining, forestry, construction and heavy industry. It can be used for the manufacture of cutters, buckets, bulldozers, diggers, crushers, conveyors and other heavy machinery. It is also used for the manufacture of industrial parts such as pulleys, gears, shafts, and other components. NM400 steel plate can also be used for the manufacture of bridges, buildings, ships, and other structures.
NM400 is one kind of Chinese wear/abrasion-resistant steel plate, which is well-received in the middle east and Africa. An NM400 wear-resistant steel was hot rolled and then the plates were heat-treated by direct quenching and tempering and reheat quenching and tempering techniques, respectively. The impact test was carried out with an instrumented impact tester. The microstructure and fracture surface were investigated by a combination of optical microscopy, transmission electron microscopy, and scanning electron microscopy methods. With high mechanical strength, NM400 is 3 times to 5 times more than common low-alloy steel plates which can significantly improve surface hardness, usually achieved 360 ~ 450HB.
